We run a Qt5 application using EGLFS but can no longer capture screenshots. In a previous yocto build based on Linux 3.x we were able to use a screenshot tool which effectively just read /dev/fb0 to a file. I believe this was a change to how the underlying drivers interact with the GPU/Screen - I've started reading up on KMS/DRM. Does anyone know is there a utility/tool which I could use to capture the Qt5 application as its drawn on screen?
